A:Answer Connectivity between bar and rear seems to be fine but the volume from rears is always very low unless the bar is cranked up. The overall quality for the surround setting is amazing, but again depends on the volume being pretty high. We have only had the volume that high for action movies or with a whole room full of people so it's gonna depend on the size of your room and the environment. The samsung q8 75 inch TV has ample volume for most things that we watch but we love the cinema- quality capabilities that the whole system offers so it's really in your preferences and budget as to its worth. Overall, connectivity is not an issue.
